USB install of a 'pot' to dim or reduce the volume on a USB speaker

Hi Folks,

Might someone know how to place a 'pot' into a USB speaker circuit?   I have one speaker, every time an instructional comes on, the volume is too loud, to soft, then I have to go to control panel to increase or reduce the sound. I figured that a variable pot might work. I have the pin outs for USB, 2,3 are D-, D+, 1 vcc, 4, grnd.

I would appreciate your help,

Thanks

sorry forgot to ask,, would a 100k pot work??
You can't adjust the volume on the USB interface !

The only way would be to open up the speakers and add a volume control in there.

Hey Jack, You must wire the Pot in series with the speaker in order to adjust volume.

VCC ---> speaker GRND, ----> POT + ------> USB GRND
